However, with the increasing reliance on containers, understanding their intricacies and addressing security concerns has become paramount. In this blog, we will delve into the fundamental concept of containers and explore the crucial security challenges they pose. Additionally, we will introduce a cutting-edge solution from our technology partner, Prevasio, that empowers organizations to fortify their containerized environments. Understanding containers At its core, a container is a standardized software package that seamlessly bundles and isolates applications for deployment. By encapsulating an application’s code and dependencies, containers ensure consistent performance across diverse computing environments. Notably, containers share access to an operating system (OS) kernel without the need for traditional virtual machines (VMs), making them an ideal choice for running microservices or large-scale applications. Security concerns in containers Container security encompasses a spectrum of risks, ranging from misconfigured privileges to malware infiltration in container images. Key concerns include using vulnerable container images, lack of visibility into container overlay networks, and the potential spread of malware between containers and operating systems. Recognizing these challenges is the first step towards building a robust security strategy for containerized environments. Introducing Prevasio’s innovative solution In collaboration with our technology partner Prevasio, we’ve identified an advanced approach to mitigating container security risks. Prevasio’s Cloud-Native Application Protection Platform (CNAPP) is an unparalleled, agentless solution designed to enhance visibility into security and compliance gaps. This empowers cloud operations and security teams to prioritize risks and adhere to internet security benchmarks effectively. Dynamic threat protection for containers Prevasio’s focus on threat protection for containers involves a comprehensive static and dynamic analysis. In the static analysis phase, Prevasio meticulously scans packages for malware and known vulnerabilities, ensuring that container images are free from Common Vulnerabilities and Exposures (CVEs) or viruses during the deployment process.

All organizations eventually inherit outdated technology infrastructure. As new technology becomes available, old apps and services... Firewall Change Management The Application Migration Checklist Asher Benbenisty 2 min read Asher Benbenisty Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 10/25/23 Published All organizations eventually inherit outdated technology infrastructure. As new technology becomes available, old apps and services become increasingly expensive to maintain. That expense can come in a variety of forms: Decreased productivity compared to competitors using more modern IT solutions. Greater difficulty scaling IT asset deployments and managing the device life cycle . Security and downtime risks coming from new vulnerabilities and emerging threats. Cloud computing is one of the most significant developments of the past decade. Organizations are increasingly moving their legacy IT assets to new environments hosted on cloud services like Amazon Web Services or Microsoft Azure. Cloud migration projects enable organizations to dramatically improve productivity, scalability, and security by transforming on-premises applications to cloud-hosted solutions. However, cloud migration projects are among the most complex undertakings an organization can attempt. Some reports state that nine out of ten migration projects experience failure or disruption at some point, and only one out of four meet their proposed deadlines. The better prepared you are for your application migration project , the more likely it is to succeed. Keep the following migration checklist handy while pursuing this kind of initiative at your company. Step 1: Assessing Your Applications The more you know about your legacy applications and their characteristics, the more comprehensive you can be with pre-migration planning. Start by identifying the legacy applications that you want to move to the cloud. Pay close attention to the dependencies that your legacy applications have. You will need to ensure the availability of those resources in an IT environment that is very different from the typical on-premises data center. You may need to configure cloud-hosted resources to meet specific needs that are unique to your organization and its network architecture. Evaluate the criticality of each legacy application you plan on migrating to the cloud. You will have to prioritize certain applications over others, minimizing disruption while ensuring the cloud-hosted infrastructure can support the workload you are moving to. There is no one-size-fits-all solution to application migration. The inventory assessment may bring new information to light and force you to change your initial approach. It’s best that you make these accommodations now rather than halfway through the application migration project. Step 2: Choosing the Right Migration Strategy Once you know what applications you want to move to the cloud and what additional dependencies must be addressed for them to work properly, you’re ready to select a migration strategy. These are generalized models that indicate how you’ll transition on-premises applications to cloud-hosted ones in the context of your specific IT environment. Some of the options you should gain familiarity with include: Lift and Shift (Rehosting). This option enables you to automate the migration process using tools like CloudEndure Migration, AWS VM Import/Export, and others. The lift and shift model is well-suited to organizations that need to migrate compatible large-scale enterprise applications without too many additional dependencies, or organizations that are new to the cloud. Replatforming. This is a modified version of the lift and shift model. Essentially, it introduces an additional step where you change the configuration of legacy apps to make them better-suited to the cloud environment. By adding a modernization phase to the process, you can leverage more of the cloud’s unique benefits and migrate more complex apps. Refactoring/Re-architecting. This strategy involves rewriting applications from scratch to make them cloud-native. This allows you to reap the full benefits of cloud technology. Your new applications will be scalable, efficient, and agile to the maximum degree possible. However, it’s a time-consuming, resource-intensive project that introduces significant business risk into the equation. Repurchasing. This is where the organization implements a fully mature cloud architecture as a managed service. It typically relies on a vendor offering cloud migration through the software-as-a-service (SaaS) model. You will need to pay licensing fees, but the technical details of the migration process will largely be the vendor’s responsibility. This is an easy way to add cloud functionality to existing business processes, but it also comes with the risk of vendor lock-in. Step 3: Building Your Migration Team The success of your project relies on creating and leading a migration team that can respond to the needs of the project at every step. There will be obstacles and unexpected issues along the way – a high-quality team with great leadership is crucial for handling those problems when they arise. Before going into the specifics of assembling a great migration team, you’ll need to identify the key stakeholders who have an interest in seeing the project through. This is extremely important because those stakeholders will want to see their interests represented at the team level. If you neglect to represent a major stakeholder at the team level, you run the risk of having major, expensive project milestones rejected later on. Not all stakeholders will have the same level of involvement, and few will share the same values and goals. Managing them effectively means prioritizing the values and goals they represent, and choosing team members accordingly. Your migration team will consist of systems administrators, technical experts, and security practitioners, and include input from many other departments. You’ll need to formalize a system of communicating inside the core team and messaging stakeholders outside of it. You may also wish to involve end users as a distinct part of your migration team and dedicate time to addressing their concerns throughout the process. Keep team members’ stakeholder alignments and interests in mind when assigning responsibilities. For example, if a particular configuration step requires approval from the finance department, you’ll want to make sure that someone representing that department is involved from the beginning. Step 4: Creating a Migration Plan It’s crucial that every migration project follows a comprehensive plan informed by the needs of the organization itself. Organizations pursue cloud migration for many different reasons – your plan should address the problems you expect cloud-hosted technology to solve. This might mean focusing on reducing costs, enabling entry into a new market, or increasing business agility – or all three. You may have additional reasons for pursuing an application migration plan. This plan should also include data mapping . Choosing the right application performance metrics now will help make the decision-making process much easier down the line. Some of the data points that cloud migration specialists recommend capturing include: Duration highlights the value of employee labor-hours as they perform tasks throughout the process. Operational duration metrics can tell you how much time project managers spend planning the migration process, or whether one phase is taking much longer than another, and why. Disruption metrics can help identify user experience issues that become obstacles to onboarding and full adoption. Collecting data about the availability of critical services and the number of service tickets generated throughout the process can help you gauge the overall success of the initiative from the user’s perspective. Cost includes more than data transfer rates. Application migration initiatives also require creating dependency mappings, changing applications to make them cloud-native, and significant administrative costs. Up to 50% of your migration’s costs pay for labor , and you’ll want to keep close tabs on those costs as the process goes on. Infrastructure metrics like CPU usage, memory usage, network latency, and load balancing are best captured both before and after the project takes place. This will let you understand and communicate the value of the project in its entirety using straightforward comparisons. Application performance metrics like availability figures, error rates, time-outs and throughput will help you calculate the value of the migration process as a whole. This is another post-cloud migration metric that can provide useful before-and-after data. You will also want to establish a series of cloud service-level agreements (SLAs) that ensure a predictable minimum level of service is maintained. This is an important guarantee of the reliability and availability of the cloud-hosted resources you expect to use on a daily basis. Step 5: Mapping Dependencies Mapping dependencies completely and accurately is critical to the success of any migration project. If you don’t have all the elements in your software ecosystem identified correctly, you won’t be able to guarantee that your applications will work in the new environment. Application dependency mapping will help you pinpoint which resources your apps need and allow you to make those resources available. You’ll need to discover and assess every workload your organization undertakes and map out the resources and services it relies on. This process can be automated, which will help large-scale enterprises create accurate maps of complex interdependent processes. In most cases, the mapping process will reveal clusters of applications and services that need to be migrated together. You will have to identify the appropriate windows of opportunity for performing these migrations without disrupting the workloads they process. This often means managing data transfer and database migration tasks and carrying them out in a carefully orchestrated sequence. You may also discover connectivity and VPN requirements that need to be addressed early on. For example, you may need to establish protocols for private access and delegate responsibility for managing connections to someone on your team. Project stakeholders may have additional connectivity needs, like VPN functionality for securing remote connections. These should be reflected in the application dependency mapping process. Multi-cloud compatibility is another issue that will demand your attention at this stage. If your organization plans on using multiple cloud providers and configuring them to run workloads specific to their platform, you will need to make sure that the results of these processes are communicated and stored in compatible formats. Step 6: Selecting a Cloud Provider Once you fully understand the scope and requirements of your application migration project, you can begin comparing cloud providers. Amazon, Microsoft, and Google make up the majority of all public cloud deployments, and the vast majority of organizations start their search with one of these three. Amazon AW S has the largest market share, thanks to starting its cloud infrastructure business several years before its major competitors did. Amazon’s head start makes finding specialist talent easier, since more potential candidates will have familiarity with AWS than with Azure or Google Cloud. Many different vendors offer services through AWS, making it a good choice for cloud deployments that rely on multiple services and third-party subscriptions. Microsoft Azure has a longer history serving enterprise customers, even though its cloud computing division is smaller and younger than Amazon’s. Azure offers a relatively easy transition path that helps enterprise organizations migrate to the cloud without adding a large number of additional vendors to the process. This can help streamline complex cloud deployments, but also increases your reliance on Microsoft as your primary vendor. Google Cloud is the third runner-up in terms of market share. It continues to invest in cloud technologies and is responsible for a few major innovations in the space – like the Kubernetes container orchestration system. Google integrates well with third-party applications and provides a robust set of APIs for high-impact processes like translation and speech recognition. Your organization’s needs will dictate which of the major cloud providers offers the best value. Each provider has a different pricing model, which will impact how your organization arrives at a cost-effective solution. Cloud pricing varies based on customer specifications, usage, and SLAs, which means no single provider is necessarily “the cheapest” or “the most expensive” – it depends on the context. Additional cost considerations you’ll want to take into account include scalability and uptime guarantees. As your organization grows, you will need to expand its cloud infrastructure to accommodate more resource-intensive tasks. This will impact the cost of your cloud subscription in the future. Similarly, your vendor’s uptime guarantee can be a strong indicator of how invested it is in your success. Given all vendors work on the shared responsibility model, it may be prudent to consider an enterprise data backup solution for peace of mind. Step 7: Application Refactoring If you choose to invest time and resources into refactoring applications for the cloud, you’ll need to consider how this impacts the overall project. Modifying existing software to take advantage of cloud-based technologies can dramatically improve the efficiency of your tech stack, but it will involve significant risk and up-front costs. Some of the advantages of refactoring include: Reduced long-term costs. Developers refactor apps with a specific context in mind. The refactored app can be configured to accommodate the resource requirements of the new environment in a very specific manner. This boosts the overall return of investing in application refactoring in the long term and makes the deployment more scalable overall. Greater adaptability when requirements change . If your organization frequently adapts to changing business requirements, refactored applications may provide a flexible platform for accommodating unexpected changes. This makes refactoring attractive for businesses in highly regulated industries, or in scenarios with heightened uncertainty. Improved application resilience . Your cloud-native applications will be decoupled from their original infrastructure. This means that they can take full advantage of the benefits that cloud-hosted technology offers. Features like low-cost redundancy, high-availability, and security automation are much easier to implement with cloud-native apps. Some of the drawbacks you should be aware of include: Vendor lock-in risks . As your apps become cloud-native, they will naturally draw on cloud features that enhance their capabilities. They will end up tightly coupled to the cloud platform you use. You may reach a point where withdrawing those apps and migrating them to a different provider becomes infeasible, or impossible. Time and talent requirements . This process takes a great deal of time and specialist expertise. If your organization doesn’t have ample amounts of both, the process may end up taking too long and costing too much to be feasible. Errors and vulnerabilities . Refactoring involves making major changes to the way applications work. If errors work their way in at this stage, it can deeply impact the usability and security of the workload itself. Organizations can use cloud-based templates to address some of these risks, but it will take comprehensive visibility into how applications interact with cloud security policies to close every gap. Step 8: Data Migration There are many factors to take into consideration when moving data from legacy applications to cloud-native apps. Some of the things you’ll need to plan for include: Selecting the appropriate data transfer method . This depends on how much time you have available for completing the migration, and how well you plan for potential disruptions during the process. If you are moving significant amounts of data through the public internet, sidelining your regular internet connection may be unwise. Offline transfer doesn’t come with this risk, but it will include additional costs. Ensuring data center compatibility. Whether transferring data online or offline, compatibility issues can lead to complex problems and expensive downtime if not properly addressed. Your migration strategy should include a data migration testing strategy that ensures all of your data is properly formatted and ready to use the moment it is introduced to the new environment. Utilizing migration tools for smooth data transfer . The three major cloud providers all offer cloud migration tools with multiple tiers and services. You may need to use these tools to guarantee a smooth transfer experience, or rely on a third-party partner for this step in the process. Step 9: Configuring the Cloud Environment By the time your data arrives in its new environment, you will need to have virtual machines and resources set up to seamlessly take over your application workloads and processes. At the same time, you’ll need a comprehensive set of security policies enforced by firewall rules that address the risks unique to cloud-hosted infrastructure. As with many other steps in this checklist, you’ll want to carefully assess, plan, and test your virtual machine deployments before deploying them in a live production environment. Gather information about your source and target environment and document the workloads you wish to migrate. Set up a test environment you can use to make sure your new apps function as expected before clearing them for live production. Similarly, you may need to configure and change firewall rules frequently during the migration process. Make sure that your new deployments are secured with reliable, well-documented security policies. If you skip the documentation phase of building your firewall policy, you run the risk of introducing security vulnerabilities into the cloud environment, and it will be very difficult for you to identify and address them later on. You will also need to configure and deploy network interfaces that dictate where and when your cloud environment will interact with other networks, both inside and outside your organization. This is your chance to implement secure network segmentation that protects mission-critical assets from advanced and persistent cyberattacks. This is also the best time to implement disaster recovery mechanisms that you can rely on to provide business continuity even if mission-critical assets and apps experience unexpected downtime. Step 10: Automating Workflows Once your data and apps are fully deployed on secure cloud-hosted infrastructure, you can begin taking advantage of the suite of automation features your cloud provider offers. Depending on your choice of migration strategy, you may be able to automate repetitive tasks, streamline post-migration processes, or enhance the productivity of entire departments using sophisticated automation tools. In most cases, automating routine tasks will be your first priority. These automations are among the simplest to configure because they largely involve high-volume, low-impact tasks. Ideally, these tasks are also isolated from mission-critical decision-making processes. If you established a robust set of key performance indicators earlier on in the migration project, you can also automate post-migration processes that involve capturing and reporting these data points. Your apps will need to continue ingesting and processing data, making data validation another prime candidate for workflow automation. Cloud-native apps can ingest data from a wide range of sources, but they often need some form of validation and normalization to produce predictable results. Ongoing testing and refinement will help you make the most of your migration project moving forward.

Firewall Change Management To NAT or not to NAT – It’s not really a question Prof. Avishai Wool 2 min read Prof. Avishai Wool Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 11/26/13 Published NAT Network Security I came across some discussions regarding Network Address Translation (NAT) and its impact on security and the network. Specifically the premise that “ NAT does not add any real security to a network while it breaks almost any good concepts of a structured network design ” is what I’d like to address. When it comes to security, yes, NAT is a very poor protection mechanism and can be circumvented in many ways. It causes headaches to network administrators. So now that we’ve quickly summarized all that’s bad about NAT, let’s address the realization that most organizations use NAT because they HAVE to, not because it’s so wonderful. The alternative to using NAT has a prohibitive cost and is possibly impossible. To dig into what I mean, let’s walk through the following scenario… Imagine you have N devices in your network that need an IP address (every computer, printer, tablet, smartphone, IP phone, etc. that belongs to your organization and its guests). Without NAT you would have to purchase N routable IP addresses from your ISP. The costs would skyrocket! At AlgoSec we run a 120+ employee company in numerous countries around the globe. We probably use 1000 IP addresses. We pay for maybe 3 routable IP addresses and NAT away the rest. Without NAT the operational cost of our IP infrastructure would go up by a factor of x300. NAT Security With regards to NAT’s impact on security, just because NAT is no replacement for a proper firewall doesn’t mean it’s useless. Locking your front door also provides very low-grade security – people still do it, since it’s a lot better than not locking your front door.

Digital Transformation Modernizing your infrastructure without neglecting security Kyle Wickert 2 min read Kyle Wickert Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 8/19/21 Published Kyle Wickert explains how organizations can balance the need to modernize their networks without compromising security For businesses of all shapes and sizes, the inherent value in moving enterprise applications into the cloud is beyond question. The ability to control computing capability at a more granular level can lead to significant cost savings, not to mention the speed at which new applications can be provisioned. Having a modern cloud-based infrastructure makes businesses more agile, allowing them to capitalize on market forces and other new opportunities much quicker than if they depended on on-premises, monolithic architecture alone. However, there is a very real risk that during the goldrush to modernized infrastructures, particularly during the pandemic when the pressure to migrate was accelerated rapidly, businesses might be overlooking the potential blind spot that threatens all businesses indiscriminately, and that is security. One of the biggest challenges for business leaders over the past decade has been managing the delicate balance between infrastructure upgrades and security. Our recent survey found that half of organizations who took part now run over 41% of workloads in the public cloud, and 11% reported a cloud security incident in the last twelve months. If businesses are to succeed and thrive in 2021 and beyond, they must learn how to walk this tightrope effectively. Let’s consider the highs and lows of modernizing legacy infrastructures, and the ways to make it a more productive experience. What are the risks in moving to the cloud? With cloud migration comes risk. Businesses that move into the cloud actually stand to lose a great deal if the process isn’t managed effectively. Moreover, they have some important decisions to make in terms of how they handle application migration. Do they simply move their applications and data into the cloud as they are as a ‘lift and shift’, or do they seek to take a more cloud-native approach and rebuild applications in the cloud to take full advantage of its myriad benefits? Once a business has started this move toward the cloud, it’s very difficult to rewind the process and unpick mistakes that may have been made, so planning really is critical. Then there’s the issue of attack surface area. Legacy on-premises applications might not be the leanest or most efficient, but they are relatively secure by default due to their limited exposure to external environments. Moving said applications onto the cloud has countless benefits to agility, efficiency, and cost, but it also increases the attack surface area for potential hackers. In other words, it gives bots and bad actors a larger target to hit. One of the many traps that businesses fall into is thinking that just because an application is in the cloud, it must be automatically secure. In fact, the reverse is true unless proper due diligence is paid to security during the migration process. The benefits of an app-centric approach One of the ways in which AlgoSec helps its customer master security in the cloud is by approaching it from an app-centric perspective. By understanding how a business uses its applications, including its connectivity paths through the cloud, data centers and SDN fabrics, we can build an application model that generates actionable insights such as the ability to create policy-based risks instead of leaning squarely on firewall controls. This is of particular importance when moving legacy applications onto the cloud. The inherent challenge here is that a business is typically taking a vulnerable application and making it even more vulnerable by moving it off-premise, relying solely on the cloud infrastructure to secure it. To address this, businesses should rank applications in order of sensitivity and vulnerability. In doing so, they may find some quick wins in terms of moving modern applications into the cloud that have less sensitive data. Once these short-term gains are dealt with, NetSecOps can focus on the legacy applications that contain more sensitive data which may require more diligence, time, and focus to move or rebuild securely. Migrating applications to the cloud is no easy feat and it can be a complex process even for the most technically minded NetSecOps. Automation takes a large proportion of the hard work away and enables teams to manage cloud environments efficiently while orchestrating changes across an array of security controls. It brings speed and accuracy to managing security changes and accelerates audit preparation for continuous compliance. Automation also helps organizations overcome skills gaps and staffing limitations. We are likely to see conflict between modernization and security for some time. On one hand, we want to remove the constraints of on-premises infrastructure as quickly as possible to leverage the endless possibilities of cloud. On the other hand, we have to safeguard against the opportunistic hackers waiting on the fray for the perfect time to strike. By following the guidelines set out in front of them, businesses can modernize without compromise.

Firewall Policy Management Firewall Traffic Analysis: The Complete Guide Asher Benbenisty 2 min read Asher Benbenisty Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 10/24/23 Published What is Firewall Traffic Analysis? Firewall traffic analysis (FTA) is a network security operation that grants visibility into the data packets that travel through your network’s firewalls. Cybersecurity professionals conduct firewall traffic analysis as part of wider network traffic analysis (NTA) workflows. The traffic monitoring data they gain provides deep visibility into how attacks can penetrate your network and what kind of damage threat actors can do once they succeed. NTA vs. FTA Explained NTA tools provide visibility into things like internal traffic inside the data center, inbound VPN traffic from external users, and bandwidth metrics from Internet of Things (iOT) endpoints. They inspect on-premises devices like routers and switches, usually through a unified, vendor-agnostic interface. Network traffic analyzers do inspect firewalls, but might stop short of firewall-specific network monitoring and management. FTA tools focus more exclusively on traffic patterns through the organization’s firewalls. They provide detailed information on how firewall rules interact with traffic from different sources. This kind of tool might tell you how a specific Cisco firewall conducts deep packet inspection on a certain IP address, and provide broader metrics on how your firewalls operate overall. It may also provide change management tools designed to help you optimize firewall rules and security policies . Firewall Rules Overview Your firewalls can only protect against security threats effectively when they are equipped with an optimized set of rules. These rules determine which users are allowed to access network assets and what kind of network activity is allowed. They play a major role in enforcing network segmentation and enabling efficient network management. Analyzing device policies for an enterprise network is a complex and time-consuming task. Minor mistakes can lead to critical risks remaining undetected and expose network devices to cyberattacks. For this reason, many security leaders use automated risk management solutions that include firewall traffic analysis. These tools perform a comprehensive analysis of firewall rules and communicate the risks of specific rules across every device on the network. This information is important because it will inform the choices you make during real-time traffic analysis. Having a comprehensive view of your security risk profile allows you to make meaningful changes to your security posture as you analyze firewall traffic. Performing Real-Time Traffic Analysis AlgoSec Firewall Analyzer captures information on the following traffic types: External IP addresses Internal IP addresses (public and private, including NAT addresses) Protocols (like TCP/IP, SMTP, HTTP, and others) Port numbers and applications for sources and destinations Incoming and outgoing traffic Potential intrusions The platform also supports real-time network traffic analysis and monitoring. When activated, it will periodically inspect network devices for changes to their policy rules, object definitions, audit logs, and more. You can view the changes detected for individual devices and groups, and filter the results to find specific network activities according to different parameters. For any detected change, Firewall Analyzer immediately aggregates the following data points: Device – The device where the changes happened. Date/Time – The exact time when the change was made. Changed by – Tells you which administrator performed the change. Summary – Lists the network assets impacted by the change. Many devices supported by Firewall Analyzer are actually systems of devices that work together. You can visualize the relationships between these assets using the device tree format. This presents every device as a node in the tree, giving you an easy way to manage and view data for individual nodes, parents nodes, and global categories. For example, Firewall Analyzer might discover a redundant rule copied across every firewall in your network. If its analysis shows that the rule triggers frequently, it might recommend moving to a higher node on the device tree. If it turns out the rule never triggers, it may recommend adjusting the rule or deleting it completely. If the rule doesn’t trigger because it conflicts with another firewall rule, it’s clear that some action is needed. Importance of Visualization and Reporting Open source network analysis tools typically work through a command-line interface or a very simple graphic user interface. Most of the data you can collect through these tools must be processed separately before being communicated to non-technical stakeholders. High-performance firewall analysis tools like AlgoSec Firewall Analyzer provide additional support for custom visualizations and reports directly through the platform. Visualization allows non-technical stakeholders to immediately grasp the importance of optimizing firewall policies, conducting netflow analysis, and improving the organization’s security posture against emerging threats. For security leaders reporting to board members and external stakeholders, this can dramatically transform the success of security initiatives. AlgoSec Firewall Analyzer includes a Visualize tab that allows users to create custom data visualizations. You can save these visualizations individually or combine them into a dashboard. Some of the data sources you can use to create visualizations include: Interactive searches Saved searches Other saved visualizations Traffic Analysis Metrics and Reports Custom visualizations enhance reports by enabling non-technical audiences to understand complex network traffic metrics without the need for additional interpretation. Metrics like speed, bandwidth usage, packet loss, and latency provide in-depth information about the reliability and security of the network. Analyzing these metrics allows network administrators to proactively address performance bottlenecks, network issues, and security misconfigurations. This helps the organization’s leaders understand the network’s capabilities and identify the areas that need improvement. For example, an organization that is planning to migrate to the cloud must know whether its current network infrastructure can support that migration. The only way to guarantee this is by carefully measuring network performance and proactively mitigating security risks. Network traffic analysis tools should do more than measure simple metrics like latency. They need to combine latency into complex performance indicators that show how much latency is occuring, and how network conditions impact those metrics. That might include measuring the variation in delay between individual data packets (jitter), Packet Delay Variation (PDV), and others. With the right automated firewall analysis tool, these metrics can help you identify and address security vulnerabilities as well. For example, you could automate the platform to trigger alerts when certain metrics fall outside safe operating parameters. Exploring AlgoSec’s Network Traffic Analysis Tool AlgoSec Firewall Analyzer provides a wide range of operations and optimizations to security teams operating in complex environments. It enables firewall performance improvements and produces custom reports with rich visualizations demonstrating the value of its optimizations. Some of the operations that Firewall Analyzer supports include: Device analysis and change tracking reports. Gain in-depth data on device policies, traffic, rules, and objects. It analyzes the routing table that produces a connectivity diagram illustrating changes from previous reports on every device covered. Traffic and routing queries. Run traffic simulations on specific devices and groups to find out how firewall rules interact in specific scenarios. Troubleshoot issues that emerge and use the data collected to prevent disruptions to real-world traffic. This allows for seamless server IP migration and security validation. Compliance verification and reporting. Explore the policy and change history of individual devices, groups, and global categories. Generate custom reports that meet the requirements of corporate regulatory standards like Sarbanes-Oxley, HIPAA, PCI DSS, and others. Rule cleanup and auditing. Identify firewall rules that are either unused, timed out, disabled, or redundant. Safely remove rules that fail to improve your security posture, improving the efficiency of your firewall devices. List unused rules, rules that don’t conform to company policy, and more. Firewall Analyzer can even re-order rules automatically, increasing device performance while retaining policy logic. User notifications and alerts. Discover when unexpected changes are made and find out how those changes were made. Monitor devices for rule changes and send emails to pre-assigned users with device analyses and reports. Network Traffic Analysis for Threat Detection and Response By monitoring and inspecting network traffic patterns, firewall analysis tools can help security teams quickly detect and respond to threats. Layer on additional technologies like Intrusion Detection Systems (IDS), Network Detection and Response (NDR), and Threat Intelligence feeds to transform network analysis into a proactive detection and response solution. IDS solutions can examine packet headers, usage statistics, and protocol data flows to find out when suspicious activity is taking place. Network sensors may monitor traffic that passes through specific routers or switches, or host-based intrusion detection systems may monitor traffic from within a host on the network. NDR solutions use a combination of analytical techniques to identify security threats without relying on known attack signatures. They continuously monitor and analyze network traffic data to establish a baseline of normal network activity. NDR tools alert security teams when new activity deviates too far from the baseline. Threat intelligence feeds provide live insight on the indicators associated with emerging threats. This allows security teams to associate observed network activities with known threats as they develop in real-time. The best threat intelligence feeds filter out the huge volume of superfluous threat data that doesn’t pertain to the organization in question. Firewall Traffic Analysis in Specific Environments On-Premises vs. Cloud-hosted Environments Firewall traffic analyzers exist in both on-premises and cloud-based forms. As more organizations migrate business-critical processes to the cloud, having a truly cloud-native network analysis tool is increasingly important. The best of these tools allow security teams to measure the performance of both on-premises and cloud-hosted network devices, gathering information from physical devices, software platforms, and the infrastructure that connects them. Securing the Internet of Things It’s also important that firewall traffic analysis tools take Internet of Things (IoT) devices in consideration. These should be grouped separately from other network assets and furnished with firewall rules that strictly segment them. Ideally, if threat actors compromise one or more IoT devices, network segmentation won’t allow the attack to spread to other parts of the network. Conducting firewall analysis and continuously auditing firewall rules ensures that the barriers between network segments remain viable even if peripheral assets (like IoT devices) are compromised. Microsoft Windows Environments Organizations that rely on extensive Microsoft Windows deployments need to augment the built-in security capabilities that Windows provides. On its own, Windows does not offer the kind of in-depth security or visibility that organizations need. Firewall traffic analysis can play a major role helping IT decision-makers deploy technologies that improve the security of their Windows-based systems. Troubleshooting and Forensic Analysis Firewall analysis can provide detailed information into the causes of network problems, enabling IT professionals to respond to network issues more quickly. There are a few ways network administrators can do this: Analyzing firewall logs. Log data provides a wealth of information on who connects to network assets. These logs can help network administrators identify performance bottlenecks and security vulnerabilities that would otherwise go unnoticed. Investigating cyberattacks. When threat actors successfully breach network assets, they can leave behind valuable data. Firewall analysis can help pinpoint the vulnerabilities they exploited, providing security teams with the data they need to prevent future attacks. Conducting forensic analysis on known threats. Network traffic analysis can help security teams track down ransomware and malware attacks. An organization can only commit resources to closing its security gaps after a security professional maps out the killchain used by threat actors to compromise network assets. Key Integrations Firewall analysis tools provide maximum value when integrated with other security tools into a coherent, unified platform. Security information and event management (SIEM) tools allow you to orchestrate network traffic analysis automations with machine learning-enabled workflows to enable near-instant detection and response. Deploying SIEM capabilities in this context allows you to correlate data from different sources and draw logs from devices across every corner of the organization – including its firewalls. By integrating this data into a unified, centrally managed system, security professionals can gain real-time information on security threats as they emerge. AlgoSec’s Firewall Analyzer integrates seamlessly with leading SIEM solutions, allowing security teams to monitor, share, and update firewall configurations while enriching security event data with insights gleaned from firewall logs. Firewall Analyzer uses a REST API to transmit and receive data from SIEM platforms, allowing organizations to program automation into their firewall workflows and manage their deployments from their SIEM.

(and How to Apply CIS Benchmarks) Rony Moshkovich 2 min read Rony Moshkovich Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 6/20/23 Published CIS provides best practices to help companies like yours improve their cloud security posture. You’ll protect your systems against various threats by complying with its benchmark standards. This post will walk you through CIS benchmarks, their development, and the kinds of systems they apply to. We will also discuss the significance of CIS compliance and how Prevasio may help you achieve it. What are CIS benchmarks? CIS stands for Center for Internet Security . It’s a nonprofit organization that aims to improve companies’ cybersecurity readiness and response. Founded in 2000, the CIS comprises cybersecurity experts from diverse backgrounds. They have the common goal of enhancing cybersecurity resilience and reducing security threats. CIS compliance means adhering to the Center for Internet Security (CIS) benchmarks. CIS benchmarks are best practices and guidelines to help you build a robust cloud security strategy. These CIS benchmarks give a detailed road map for protecting a business’s IT infrastructure. They also encompass various platforms, such as web servers or cloud bases. The CIS benchmarks are frequently called industry standards. They are normally in line with other regulatory organizations, such as ISO, NIST, and HIPAA. Many firms adhere to CIS benchmarks to ensure they follow industry standards. They also do this to show their dedication to cybersecurity to clients and stakeholders. The CIS benchmarks and CIS controls are always tested through on-premises analysis by leading security firms. This ensures that CIS releases standards that are effective at mitigating cyber risks. How are the CIS benchmarks developed? A community of cybersecurity professionals around the world cooperatively develops CIS benchmarks. They exchange their knowledge, viewpoints, and experiences on a platform provided by CIS. The end result is consensus-based best practices that will protect various IT systems. The CIS benchmark development process typically involves the following steps: 1. Identify the technology: The first step is to identify the system or technology that has to be protected. This encompasses a range of applications. It can be an operating system, database, web server, or cloud environment. 2. Define the scope: The following stage is to specify the benchmark’s parameters. It involves defining what must be implemented for the technology to be successfully protected. They may include precise setups, guidelines, and safeguards. 3. Develop recommendations: Next, a community of cybersecurity experts will identify ideas for safeguarding the technology. These ideas are usually based on current best practices, norms, and guidelines. They may include the minimum security requirements and measures to be taken. 4. Expert consensus review: Thereafter, a broader group of experts and stakeholders assess the ideas. They will offer comments and suggestions for improvement. This level aims to achieve consensus on the appropriate technical safeguards. 5. Pilot testing: The benchmark is then tested in a real-world setting. At this point, CIS aims to determine its efficacy and spot any problems that need fixing. 6. Publication and maintenance: The CIS will publish the benchmark once it has been improved and verified. The benchmark will constantly be evaluated and updated to keep it current and useful for safeguarding IT systems. What are the CIS benchmark levels? CIS benchmarks are divided into three levels based on the complexity of an IT system. It’s up to you to choose the level you need based on the complexity of your IT environment. Each level of the benchmarks offers better security recommendations than the previous level. The following are the distinct categories that benchmarks are divided into: Level 1 This is the most basic level of CIS standards. It requires organizations to set basic security measures to reduce cyber threats. Some CIS guidelines at this level include password rules, system hardening, and risk management. The level 1 CIS benchmarks are ideal for small businesses with basic IT systems. Level 2 This is the intermediate level of the CIS benchmarks. It is suitable for small to medium businesses that have complex IT systems. The Level 2 CIS standards offer greater security recommendations to your cloud platform. It has guidelines for network segmentation, authentication, user permissions, logging, and monitoring. At this level, you’ll know where to focus your remediation efforts if you spot a vulnerability in your system. Level 2 also covers data protection topics like disaster recovery plans and encryption. Level 3 Level 3 is the most advanced level of the CIS benchmarks. It offers the highest security recommendations compared to the other two. Level 3 also offers the Security Technical Implementation Guide (STIG) profiles for companies. STIG are configuration guidelines developed by the Defense Information Systems Agency. These security standards help you meet US government requirements. This level is ideal for large organizations with the most sensitive and vital data. These are companies that must protect their IT systems from complex security threats. It offers guidelines for real-time security analytics, safe cloud environment setups, and enhanced threat detection. What types of systems do CIS benchmarks apply to? The CIS benchmarks are applicable to many IT systems used in a cloud environment. The following are examples of systems that CIS benchmarks can apply to: Operating systems: CIS benchmarks offer standard secure configurations for common operating systems, including Amazon Linux, Windows Servers, macOS, and Unix. They address network security, system hardening, and managing users and accounts. Cloud infrastructure: CIS benchmarks can help protect various cloud infrastructures, including public, private, and multi-cloud. They recommend guidelines that safeguard cloud systems by various cloud service providers. For example, network security, access restrictions, and data protection. The benchmarks cover cloud systems such as Amazon Web Services (AWS), Microsoft Azure, IBM, Oracle, and Google Cloud Platform. Server software: CIS benchmarks provide secure configuration baselines for various servers, including databases (SQL), DNS, Web, and authentication servers. The baselines cover system hardening, patch management, and access restrictions. Desktop software: Desktop apps such as music players, productivity programs, and web browsers can be weak points in your IT system. CIS benchmarks offer guidelines to help you protect your desktop software from vulnerabilities. They may include patch management, user and account management, and program setup. Mobile devices: The CIS benchmarks recommend safeguarding endpoints such as tablets and mobile devices. The standards include measures for data protection, account administration, and device configuration. Network devices: CIS benchmarks also involve network hardware, including switches, routers, and firewalls. Some standards for network devices include access restrictions, network segmentation, logging, and monitoring. Print devices: CIS benchmarks also cover print devices like printers and scanners. The CIS benchmark baselines include access restrictions, data protection, and firmware upgrades. Why is CIS compliance important? CIS compliance helps you maintain secure IT systems. It does this by helping you adhere to globally recognized cybersecurity standards. CIS benchmarks cover various IT systems and product categories, such as cloud infrastructures. So by ensuring CIS benchmark compliance, you reduce the risk of cyber threats to your IT systems. Achieving CIS compliance has several benefits: 1. Your business will meet internationally accepted cybersecurity standards . The CIS standards are developed through a consensus review process. This means they are founded on the most recent threat intelligence and best practices. So you can rely on the standards to build a solid foundation for securing your IT infrastructure. 2. It can help you meet regulatory compliance requirements for other important cybersecurity frameworks . CIS standards can help you prove that you comply with other industry regulations. This is especially true for companies that handle sensitive data or work in regulated sectors. CIS compliance is closely related to other regulatory compliances such as NIST, HIPAA, and PCI DSS. By implementing the CIS standards, you’ll conform to the applicable industry regulations. 3. Achieving CIS continuous compliance can help you lower your exposure to cybersecurity risks . In the process, safeguard your vital data and systems. This aids in preventing data breaches, malware infections, and other cyberattacks. Such incidents could seriously harm your company’s operations, image, and financial situation. A great example is the Scottish Oil giant, SSE. It had to pay €10M in penalties for failing to comply with a CIS standard in 2013. 4. Abiding by the security measures set by CIS guidelines can help you achieve your goals faster as a business. The guidelines cover the most important and frequently attacked areas of IT infrastructure. 5. CIS compliance enhances your general security posture. It also decreases the time and resources needed to maintain security. It does this by providing uniform security procedures across various platforms. How to achieve CIS compliance? Your organization can achieve CIS compliance by conforming to the guidelines of the CIS benchmarks and CIS controls. Each CIS benchmark usually includes a description of a recommended configuration. It also usually contains a justification for the implementation of the configuration. Finally, it offers step-by-step instructions on how to carry out the recommendation manually. While the standards may seem easy to implement manually, they may consume your time and increase the chances of human errors. That is why most security teams prefer using tools to automate achieving and maintaining CIS compliance. CIS hardened images are great examples of CIS compliance automation tools. They are pre-configured images that contain all the necessary recommendations from CIS benchmarks. You can be assured of maintaining compliance by using these CIS hardened images in your cloud environment. You can also use CSPM tools to automate achieving and maintaining CIS compliance.

Cloud Security Understanding and Preventing Kubernetes Attacks and Threats Ava Chawla 2 min read Ava Chawla Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 10/20/21 Published As the most widely adapted open-source container software, Kubernetes provides businesses with efficient processes to schedule, deploy, and scale containers across different machines. The bad news is that cybercriminals have figured out how to exploit the platform’s vulnerabilities , resulting in catastrophic network intrusions across many company infrastructures. A recent report revealed that 94% of respondents reported security incidents in Kubernetes environments. The question is, what is behind this surge of Kubernetes attacks, and how can they be prevented? How Kubernetes is Vulnerable As a container-based platform, a new set of vulnerabilities, permission issues, and specific images set the stage for the increase in attacks. The threats have included fileless malware in containers, leveraging misconfigured Docker API ports, and using container images for attacks. Misconfigured Docker API Ports Exploitation Scanning for misconfigured Docker API ports and using them for deploying images containing malware is a relatively new type of attack. The malware, designed to evade static scanning, has become a popular method to hijack compute cycles for fraudulent cryptomining. This cryptojacking activity steals CPU power to mine currencies such as Ethereum and Monero. By first identifying vulnerable front-end websites and other systems, attackers send a command through the application layer simply by manipulating a domain’s text field or through an exposed API in the website’s URL. The code then enters the container, where it is executed with commands sent to a Docker container’s shell. A wget command is executed to download the malware. To protect against this attack, enterprises must ensure their container files are not writable, establish CPU consumption limits, and enable alerts to detect interactive shell launches. DDoS Attacks With Open Docker Daemons Cybercriminals use misconfigured open Docker daemons to launch DDoS attacks using a botnet of containers. UDP flood and Slowloris were recently identified as two such types of container-based botnet attacks. A recent blog describes an anatomy of these Kubernetes attacks. The attackers first identified open Docker daemons using a scanning tool such as Shodan to scan the internet for IP addresses and find a list of hosts, open ports, and services. By uploading their own dedicated images to the Docker hub, they succeeded in deploying and remotely running the images on the host. Analyzing how the UDP flood attack was orchestrated required an inspection of the binary with IDA. This revealed the start_flood and start_tick threads. The source code for the attack was found on Github. This code revealed a try_gb parameter, with the range of 0 to 1,024, used to configure how much data to input to flood the target. However, it was discovered that attackers are able to modify this open-source code to create a self-compiled binary that floods the host with even greater amounts of UDP packets. In the case of the Slowloris attack, cybercriminals launched DDoS with the slowhttptest utility. The attackers were able to create a self-compiling binary that is unidentifiable in malware scans. Protection from these Kubernetes attacks requires vigilant assurance policies and prevention of images other than compliant ones to run in the system. Non-compliant images will then be blocked when intrusion attempts are made. Man in the Middle Attacks With LoadBalancer or ExternalIPs An attack affecting all versions of Kubernetes involves multi-tenant clusters. The most vulnerable clusters have tenants that are able to create and update services and pods. In this breach, the attacker can intercept traffic from other pods or nodes in the cluster by creating a ClusterIP service and setting the spec.externalIP’s field. Additionally, a user who is able to patch the status of a LoadBalancer service can grab traffic. The only way to mitigate this threat is to restrict access to vulnerable features. This can be done with the admission webhook container, externalip-webhook , which prevents services from using random external IPs. An alternative method is to lock external IPs with OPA Gatekeeper with this sample Constraint Templatecan. Siloscape Malware Security researcher, Daniel Prizmant, describes a newer malware attack that he calls Siloscape. Its primary goal is to escape the container that is mainly implemented in Windows server silo. The malware targets Kubernetes through Windows containers to open a backdoor into poorly configured clusters to run the malicious containers. While other malware attacks focus on cryptojacking, the Siloscape user’s motive is to go undetected and open a backdoor to the cluster for a variety of malicious activities. This is possible since Siloscape is virtually undetectable due to a lack of readable strings in the binary. This type of attack can prove catastrophic. It compromises an entire cluster running multiple cloud applications. Cybercriminals can access critical information including sign-ins, confidential files, and complete databases hosted inside the cluster. Additionally, organizations using Kubernetes clusters for testing and development can face catastrophic damage should these environments be breached. To prevent a Siloscape attack, it is crucial that administrators ensure their Kubernetes clusters are securely configured. This will prevent the malware from creating new deployments and force Siloscape to exit. Microsoft also recommends using only Hyper-V containers as a security boundary for anything relying on containerization. The Threat Matrix The MITRE ATT&CK database details additional tactics and techniques attackers are using to infiltrate Kubernetes environments to access sensitive information, mine cryptocurrency, perform DDoS attacks, and other unscrupulous activities. The more commonly used methods are as follows: 1. Kubernetes file compromise Because this file holds sensitive data such as cluster credentials, an attacker could easily gain initial access to the entire cluster. Only accept kubeconfig files from trusted sources. Others should be thoroughly inspected before they are deployed. 2. Using similar pod names Attackers create similar pod names and use random suffixes to hide them in the cluster. The pods then run malicious code and obtain access to many other resources. 3. Kubernetes Secrets intrusion Attackers exploit any misconfigurations in the cluster with the goal of accessing the API server and retrieving information from the Secrets objects. 4. Internal network access Attackers able to access a single pod that communicates with other pods or applications can move freely within the cluster to achieve their goals. 5. Using the writeable hostPath mount Attackers with permissions to create new containers can create one with a writeable hostPath volume. Kubernetes Attacks: Key Takeaways Kubernetes brings many advantages to organizations but also presents a variety of security risks, as documented above. However, by ensuring their environments are adequately protected through proper configuration and appropriately assigned permissions, the threat of Kubernetes attacks is greatly minimized. Should a container be compromised, properly assigned privileges can severely limit a cluster-wide compromise.

Tags Share this article 4/16/21 Published Tsippi Dach, Director of Communications at AlgoSec, explores the relationship between NetOps and SecOps and explains why they are the perfect partnership The IT landscape has changed beyond recognition in the past decade or so. The vast majority of businesses now operate largely in the cloud, which has had a notable impact on their agility and productivity. A recent survey of 1,900 IT and security professionals found that 41 percent or organizations are running more of their workloads in public clouds compared to just one-quarter in 2019. Even businesses that were not digitally mature enough to take full advantage of the cloud will have dramatically altered their strategies in order to support remote working at scale during the COVID-19 pandemic. However, with cloud innovation so high up the boardroom agenda, security is often left lagging behind, creating a vulnerability gap that businesses can little afford in the current heightened risk landscape. The same survey found the leading concern about cloud adoption was network security (58%). Managing organizations’ networks and their security should go hand-in-hand, but, as reflected in the survey, there’s no clear ownership of public cloud security. Responsibility is scattered across SecOps, NOCs and DevOps, and they don’t collaborate in a way that aligns with business interests. We know through experience that this siloed approach hurts security, so what should businesses do about it? How can they bridge the gap between NetOps and SecOps to keep their network assets secure and prevent missteps? Building a case for NetSecOps Today’s digital infrastructure demands the collaboration, perhaps even the convergence, of NetOps and SecOps in order to achieve maximum security and productivity. While the majority of businesses do have open communication channels between the two departments, there is still a large proportion of network and security teams working in isolation. This creates unnecessary friction, which can be problematic for service-based businesses that are trying to deliver the best possible end-user experience. The reality is that NetOps and SecOps share several commonalities. They are both responsible for critical aspects of a business and have to navigate constantly evolving environments, often under extremely restrictive conditions. Agility is particularly important for security teams in order for them to keep pace with emerging technologies, yet deployments are often stalled or abandoned at the implementation phase due to misconfigurations or poor execution. As enterprises continue to deploy software-defined networks and public cloud architecture, security has become even more important to the network team, which is why this convergence needs to happen sooner rather than later. We somehow need to insert the network security element into the NetOps pipeline and seamlessly make it just another step in the process. If we had a way to automatically check whether network connectivity is already enabled as part of the pre-delivery testing phase, that could, at least, save us the heartache of deploying something that will not work. Thankfully, there are tools available that can bring SecOps and NetOps closer together, such as Cisco ACI , Cisco Secure Workload and AlgoSec Security Management Solution . Cisco ACI, for instance, is a tightly coupled policy-driven solution that integrates software and hardware, allowing for greater application agility and data center automation. Cisco Secure Workload (previously known as Tetration), is a micro-segmentation and cloud workload protection platform that offers multi-cloud security based on a zero-trust model. When combined with AlgoSec, Cisco Secure Workload is able to map existing application connectivity and automatically generate and deploy security policies on different network security devices, such as ACI contract, firewalls, routers and cloud security groups. So, while Cisco Secure Workload takes care of enforcing security at each and every endpoint, AlgoSec handles network management. This is NetOps and SecOps convergence in action, allowing for 360-degree oversight of network and security controls for threat detection across entire hybrid and multi-vendor frameworks. While the utopian harmony of NetOps and SecOps may be some way off, using existing tools, processes and platforms to bridge the divide between the two departments can mitigate the ‘silo effect’ resulting in stronger, safer and more resilient operations. We recently hosted a webinar with Doug Hurd from Cisco and Henrik Skovfoged from Conscia discussing how you can bring NetOps and SecOps teams together with Cisco and AlgoSec.

Firewall Change Management How to secure your LAN (Local Area Network) Matthew Pascucci 2 min read Matthew Pascucci Short bio about author here Lorem ipsum dolor sit amet consectetur.

Tags Share this article 11/12/13 Published How to Secure Your Local Area Network In my last blog series we reviewed ways to protect the perimeter of your network and then we took it one layer deeper and discussed securing the DMZ . Now I’d like to examine the ways you can secure the Local Area Network, aka LAN, also known as the soft underbelly of the beast. Okay, I made that last part up, but that’s what it should be called. The LAN has become the focus of attack over the past couple years, due to companies tightening up their perimeter and DMZ. It’s very rare you’ll you see an attacker come right at you these days, when they can trick an unwitting user into clicking a weaponized link about “Cat Videos” (Seriously, who doesn’t like cat videos?!). With this being said, let’s talk about a few ways we can protect our soft underbelly and secure our network. For the first part of this blog series, let’s examine how to secure the LAN at the network layer. LAN and the Network Layer From the network layer, there are constant things that can be adjusted and used to tighten the posture of your LAN. The network is the highway where the data traverses. We need protection on the interstate just as we need protection on our network. Protecting how users are connecting to the Internet and other systems is an important topic. We could create an entire series of blogs on just this topic, but let’s try to condense it a little here. Verify that you’re network is segmented – it better be if you read my last article on the DMZ – but we need to make sure nothing from the DMZ is relying on internal services. This is a rule. Take them out now and thank us later. If this is happening, you are just asking for some major compliance and security issues to crop up. Continuing with segmentation, make sure there’s a guest network that vendors can attach to if needed. I hate when I go to a client/vendor’s site and they ask me to plug into their network. What if I was evil? What if I had malware on my laptop that’s now ripping throughout your network because I was dumb enough to click a link to a “Cat Video”? If people aren’t part of your company, they shouldn’t be connecting to your internal LAN plain and simple. Make sure you have egress filtering on your firewall so you aren’t giving complete access for users to pillage the Internet from your corporate workstation. By default users should only have access to port 80/443, anything else should be an edge case (in most environments). If users need FTP access there should be a rule and you’ll have to allow them outbound after authorization, but they shouldn’t be allowed to rush the Internet on every port. This stops malware, botnets, etc. that are communicating on random ports. It doesn’t protect everything since you can tunnel anything out of these ports, but it’s a layer! Set up some type of switch security that’s going to disable a port if there are different or multiple MAC addresses coming from a single port. This stops hubs from being installed in your network and people using multiple workstations. Also, attempt to set up NAC to get a much better understating of what’s connecting to your network while giving you complete control of those ports and access to resources from the LAN. In our next LAN security-focused blog, we’ll move from the network up the stack to the application layer.

Uncategorized Risk Management in Network Security: 7 Best Practices for 2024 Tsippi Dach 2 min read Tsippi Dach Short bio about author here Lorem ipsum dolor sit amet consectetur.

Tags Share this article 1/26/24 Published Protecting an organization against every conceivable threat is rarely possible. There is a practically unlimited number of potential threats in the world, and security leaders don’t have unlimited resources available to address them. Prioritizing risks associated with more severe potential impact allows leaders to optimize cybersecurity decision-making and improve the organization’s security posture. Cybersecurity risk management is important because many security measures come with large costs. Before you can implement security controls designed to protect against cyberattacks and other potential risks, you must convince key stakeholders to support the project. Having a structured approach to cyber risk management lets you demonstrate exactly how your proposed changes impact the organization’s security risk profile. This makes it much easier to calculate the return on cybersecurity investment – making it a valuable tool when communicating with board members and executives. Here are seven tips every security leader should keep in mind when creating a risk management strategy: Cultivate a security-conscious risk management culture Use risk registers to describe potential risks in detail Prioritize proactive, low-cost risk remediation when possible Treat risk management as an ongoing process Invest in penetration testing to discover new vulnerabilities Demonstrate risk tolerance by implementing the NIST Cybersecurity Framework Don’t forget to consider false positives in your risk assessment What is a Risk Management Strategy? The first step to creating a comprehensive risk management plan is defining risk. According to the International Organization for Standardization (ISO) risk is “the effect of uncertainty on objectives”. This definition is accurate, but its scope is too wide. Uncertainty is everywhere, including things like market conditions, natural disasters, or even traffic jams. As a cybersecurity leader, your risk management process is more narrowly focused on managing risks to information systems, protecting sensitive data, and preventing unauthorized access. Your risk management program should focus on identifying these risks, assessing their potential impact, and creating detailed plans for addressing them. This might include deploying tools for detecting cyberattacks, implementing policies to prevent them, or investing in incident response and remediation tools to help you recover from them after they occur. In many cases, you’ll be doing all of these things at once. Crucially, the information you uncover in your cybersecurity risk assessment will help you prioritize these initiatives and decide how much to spend on them. Your risk management framework will provide you with the insight you need to address high-risk, high-impact cybersecurity threats first and manage low-risk, low-impact threats later on. 7 Tips for Creating a Comprehensive Risk Management Strategy 1. Cultivate a security-conscious risk management culture No CISO can mitigate security risks on their own. Every employee counts on their colleagues, partners, and supervisors to keep sensitive data secure and prevent data breaches. Creating a risk management strategy is just one part of the process of developing a security-conscious culture that informs risk-based decision-making. This is important because many employees have to make decisions that impact security on a daily basis. Not all of these decisions are critical-severity security scenarios, but even small choices can influence the way the entire organization handles risk. For example, most organizations list their employees on LinkedIn. This is not a security threat on its own, but it can contribute to security risks associated with phishing attacks and social engineering . Cybercriminals may create spoof emails inviting employees to fake webinars hosted by well-known employees, and use the malicious link to infect employee devices with malware. Cultivating a risk management culture won’t stop these threats from happening, but it might motivate employees to reach out when they suspect something is wrong. This gives security teams much greater visibility into potential risks as they occur, and increases the chance you’ll detect and mitigate threats before they launch active cyberattacks. 2. Use risk registers to describe potential risks in detail A risk register is a project management tool that describes risks that could disrupt a project during execution. Project managers typically create the register during the project planning phase and then refer to it throughout execution. A risk register typically uses the following characteristics to describe individual risks: Description : A brief overview of the risk itself. Category: The formal classification of the risk and what it affects. Likelihood: How likely this risk is to take place. Analysis: What would happen if this risk occurred. Mitigation: What would the team need to do to respond in this scenario. Priority: How critical is this risk compared to others. The same logic applies to business initiatives both large and small. Using a risk register can help you identify and control unexpected occurrences that may derail the organization’s ongoing projects. If these projects are actively supervised by a project manager, risk registers should already exist for them. However, there may be many initiatives, tasks, and projects that do not have risk registers. In these cases, you may need to create them yourself. Part of the overall risk assessment process should include finding and consolidating these risk registers to get an idea of the kinds of disruptions that can take place at every level of the organization. You may find patterns in the types of security risks that you find described in multiple risk registers. This information should help you evaluate the business impact of common risks and find ways to mitigate those risks effectively. 3. Prioritize proactive, low-cost risk remediation when possible Your organization can’t afford to prevent every single risk there is. That would require an unlimited budget and on-demand access to technical specialist expertise. However, you can prevent certain high-impact risks using proactive, low-cost policies that can make a significant difference in your overall security posture. You should take these opportunities when they present themselves. Password policies are a common example. Many organizations do not have sufficiently robust password policies in place. Cybercriminals know this –that’s why dictionary-based credential attacks still occur. If employees are reusing passwords across accounts or saving them onto their devices in plaintext, it’s only a matter of time before hackers notice. At the same time, upgrading a password policy is not an especially expensive task. Even deploying an enterprise-wide password manager and investing in additional training may be several orders of magnitude cheaper than implementing a new SIEM or similarly complex security platform. Your cybersecurity risk assessment will likely uncover many opportunities like this one. Take a close look at things like password policies, change management , and security patch update procedures and look for easy, low-cost projects that can provide immediate security benefits without breaking your budget. Once you address these issues, you will be in a much better position to pursue larger, more elaborate security implementations. 4. Treat risk management as an ongoing process Every year, cybercriminals leverage new tactics and techniques against their victims. Your organization’s security team must be ready to address the risks of emerging malware, AI-enhanced phishing messages, elaborate supply chain attacks, and more. As hackers improve their attack methodologies, your organization’s risk profile shifts. As the level of risk changes, your approach to information security must change as well. This means developing standards and controls that adjust according to your organization’s actual information security risk environment. Risk analysis should not be a one-time event, but a continuous one that delivers timely results about where your organization is today – and where it may be in the future. For example, many security teams treat firewall configuration and management as a one-time process. This leaves them vulnerable to emerging threats that they may not have known about during the initial deployment. Part of your risk management strategy should include verifying existing security solutions and protecting them from new and emerging risks. 5. Invest in penetration testing to discover new vulnerabilities There is more to discovering new risks than mapping your organization’s assets to known vulnerabilities and historical data breaches. You may be vulnerable to zero-day exploits and other weaknesses that won’t be immediately apparent. Penetration testing will help you discover and assess risks that you can’t find out about otherwise. Penetration testing mitigates risk by pinpointing vulnerabilities in your environment and showing how hackers could exploit them. Your penetration testing team will provide a comprehensive report showing you what assets were compromised and how. You can then use this information to close those security gaps and build a stronger security posture as a result. There are multiple kinds of penetration testing. Depending on your specific scenario and environment, you may invest in: External network penetration testing focuses on the defenses your organization deploys on internet-facing assets and equipment. The security of any business application exposed to the public may be assessed through this kind of test. Internal network penetration testing determines how cybercriminals may impact the organization after they gain access to your system and begin moving laterally through it. This also applies to malicious insiders and compromised credential attacks. Social engineering testing looks specifically at how employees respond to attackers impersonating customers, third-party vendors, and internal authority figures. This will help you identify risks associated with employee security training . Web application testing focuses on your organization’s web-hosted applications. This can provide deep insight into how secure your web applications are, and whether they can be leveraged to leak sensitive information. 6. Demonstrate risk tolerance by implementing the NIST Cybersecurity Framework The National Institute of Standards and Technology publishes one of the industry’s most important compliance frameworks for cybersecurity risk mitigation. Unlike similar frameworks like PCI DSS and GDPR, the NIST Cybersecurity Framework is voluntary – you are free to choose when and how you implement its controls in your organization. This set of security controls includes a comprehensive, flexible approach to risk management. It integrates risk management techniques across multiple disciplines and combines them into an effective set of standards any organization can follow. As of 2023, the NIST Risk Management Framework focuses on seven steps: Prepare the organization to change the way it secures its information technology solutions. Categorize each system and the type of information it processes according to a risk and impact analysis/ Select which NIST SP 800-53 controls offer the best data protection for the environment. Implement controls and document their deployment. Assess whether the correct controls are in place and operating as intended. Authorize the implementation in partnership with executives, stakeholders, and IT decision-makers. Monitor control implementations and IT systems to assess their effectiveness and discover emerging risks. 7. Don’t forget to consider false positives in your risk assessment False positives refer to vulnerabilities and activity alerts that have been incorrectly flagged. They can take many forms during the cybersecurity risk assessment process – from vulnerabilities that don’t apply to your organization’s actual tech stack to legitimate traffic getting blocked by firewalls. False positives can impact risk assessments in many ways. The most obvious problem they present is skewing your assessment results. This may lead to you prioritizing security controls against threats that aren’t there. If these controls are expensive or time-consuming to deploy, you may end up having an uncomfortable conversation with key stakeholders and decision-makers later on. However, false positives are also a source of security risks. This is especially true with automated systems like next-generation firewalls , extended detection and response (XDR) solutions, and Security Orchestration, Automation, and Response (SOAR) platforms. Imagine one of these systems detects an outgoing video call from your organization. It flags the connection as suspicious and begins investigating it. It discovers the call is being made from an unusual location and contains confidential data, so it blocks the call and terminates the connection. This could be a case of data exfiltration, or it could be the company CEO presenting a report to stockholders while traveling. Most risk assessments don’t explore the potential risk of blocking high-level executive communications or other legitimate communications due to false positives. Use AlgoSec to Identify and Assess Network Security Risks More Accurately Building a comprehensive risk management strategy is not an easy task. It involves carefully observing the way your organization does business and predicting how cybercriminals may exploit those processes. It demands familiarity with almost every task, process, and technology the organization uses, and the ability to simulate attack scenarios from multiple different angles. There is no need to accomplish these steps manually. Risk management platforms like AlgoSec’s Firewall Analyzer can help you map business applications throughout your network and explore attack simulations with detailed “what-if” scenarios. Use Firewall Analyzer to gain deep insight into how your organization would actually respond to security incidents and unpredictable events, then use those insights to generate a more complete risk management approach.

Cyber Attacks & Incident Response How to improve network security (7 fundamental ways) Tsippi Dach 2 min read Tsippi Dach Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 8/9/23 Published As per Cloudwards , a new organization gets hit by ransomware every 14 seconds. This is despite the fact that global cybersecurity spending is up and is around $150 billion per year. That’s why fortifying your organization’s network security is the need of the hour. Learn how companies are proactively improving their network security with these best practices. 7 Ways to improve network security: ` 1. Change the way you measure cyber security risk Cyber threats have evolved with modern cybersecurity measures. Thus, legacy techniques to protect the network are not going to work. These techniques include measures like maturity assessment, compliance attestation, and vulnerability aging reports, among other things. While they still have a place in cybersecurity, they’re insufficient. To level up, you need greater visibility over the various risk levels. This visibility will allow you to deploy resources as per need. At the bare minimum, companies need a dashboard that lists real-time data on the number of applications, the region they’re used in, the size and nature of the database, the velocity of M&A, etc. IT teams can make better decisions since the impact of new technologies like big data and AI falls unevenly on organizations. Along with visibility, companies need transparency and precision on how the tools behave against cyberattacks. You can use the ATT&CK Framework developed by MITRE Corporation, the most trustworthy threat behavior knowledge base available today. Use it as a benchmark to test the tools’ efficiency. Measuring the tools this way helps you prepare well in advance. Another measurement technique you must adopt is measuring performance against low-probability, high-consequence attacks. Pick the events that you conclude have the least chance of occurring. Then, test the tools on such attacks. Maersk learned this the hard way. In the notPetya incident , the company came pretty close to losing all of its IT data. Imagine the consequence it’d have on the company that handles the world’s supply chain. Measuring is the only way to learn whether your current cybersecurity arrangements meet the need. 2. Use VLAN and subnets An old saying goes, ‘Don’t keep all your eggs in the same basket.’ Doing so would mean losing the basket, losing all your eggs. That is true for IT networks as well. Instead of treating your network as a whole, divide it into multiple subnetworks. There are various ways you can do that: VLAN or Virtual LAN is one of them. VLAN helps you segment a physical network without investing in additional servers or devices. The different segments can then be handled differently as per the need. For example, the accounting department will have a separate segment, and so will the marketing and sales departments. This segmentation helps enhance security and limit damage. VLAN also helps you prioritize data, networks, and devices. There will be some data that is more critical than others. The more critical data warrant better security and protection, which you can provide through a VLAN partition. Subnets are another way to segment networks. As opposed to VLAN, which separates the network at the switch level, subnets partition the network at IP level or level 3. The various subnetworks can then communicate with each other and third-party networks over IP. With the adoption of technologies like the Internet of Things (IoT), network segmentation is only going to get more critical. Each device used for data generation, like smartwatches, sensors, and cameras, can act as an entry point to your network. If the entry points are connected to sensitive data like consumers’ credit cards, it’s a recipe for disaster. You can implement VLAN or subnets in such a scenario. 3. Use NGFWs for cloud The firewall policy is at the core of cybersecurity. They’re essentially the guardians who check for intruders before letting the traffic inside the network. But with the growth of cloud technologies and the critical data they hold, traditional firewalls are no longer reliable. They can easily be passed by modern malware. You must install NGFWs or Next Generation Firewalls in your cloud to ensure total protection. These firewalls are designed specifically to counter modern cyberattacks. An NGFW builds on the capabilities of a traditional firewall. Thus, it inspects all the incoming traffic. But in addition, it has advanced capabilities like IPS (intrusion prevention system), NAT (network address translation), SPI (stateful protocol inspection), threat intelligence feeds, container protection, and SSL decryption, among others. NGFWs are also both user and application-aware. This allows them to provide context on the incoming traffic. NGFWs are important not only for cloud networks but also for hybrid networks . Malware from the cloud could easily transition into physical servers, posing a threat to the entire network. When selecting a next-gen firewall for your cloud, consider the following security features: The speed at which the firewall detects threats. Ideally, it should identify the attacks in seconds and detect data breaches within minutes. The number of deployment options available. The NGFW should be deployable on any premise, be it a physical, cloud, or virtual environment. Also, it should support different throughput speeds. The home network visibility it offers. It should report on the applications and websites, location, and users. In addition, it should show threats across the separate network in real-time. The detection capabilities. It goes without saying, but the next-gen firewall management should detect novel malware quickly and act as an anti-virus. Other functionalities that are core security requirements. Every business is different with its unique set of needs. The NGFW should fulfill all the needs. 4. Review and keep IAM updated To a great extent, who can access what determines the security level of a network. As a best practice, you should grant access to users as per their roles and requirement — nothing less, nothing more. In addition, it’s necessary to keep IAM updated as the role of users evolves. IAM is a cloud service that controls unauthorized access for users. The policies defined in this service either grant or reject resource access. You need to make sure the policies are robust. This requires you to review your IT infrastructure, the posture, and the users at the organization. Then create IAM policies and grant access as per the requirement. As already mentioned, users should have remote access to the resources they need. Take that as a rule. Along with that, uphold these important IAM principles to improve access control and overall network security strategy: Zero in on the identity It’s important to identify and verify the identity of every user trying to access the network. You can do that by centralizing security control on both user and service IDs. Adopt zero-trust Trust no one. That should be the motto when handling a company’s network security. It’s a good practice to assume every user is untrustworthy unless proven otherwise. Therefore, have a bare minimum verification process for everyone. Use MFA MFA or multi-factor authentication is another way to safeguard network security. This could mean they have to provide their mobile number or OTA pin in addition to the password. MFA can help you verify the user and add an additional security layer. Beef up password Passwords are a double-edged sword. They protect the network but also pose a threat when cracked. To prevent this, choose strong passwords meeting a certain strength level. Also, force users to update their unique passwords regularly. If possible, you can also go passwordless. This involves installing email-based or biometric login systems. Limit privileged accounts Privileged accounts are those accounts that have special capabilities to access the network. It’s important to review such accounts and limit their number. 5. Always stay in compliance Compliance is not only for pleasing the regulators. It’s also for improving your network security. Thus, do not take compliance for granted; always make your network compliant with the latest standards. Compliance requirements are conceptualized after consulting with industry experts and practitioners. They have a much better authoritative position to discuss what needs to be done at an industry level. For example, in the card sector, it’s compulsory to have continuous penetration testing done. So, when fulfilling a requirement, you adopt the best practices and security measures. The requirements don’t remain static. They evolve and change as loopholes emerge. The new set of compliance frameworks helps ensure you’re up-to-date with the latest standards. Compliance is also one of the hardest challenges to tackle. That’s because there are various types of compliances. There are government-, industry-, and product-level compliance requirements that companies must keep up with. Moreover, with hybrid networks and multi-cloud workflows, the task only gets steeper. Cloud security management tools can help in this regard to some extent. Since they grant a high level of visibility, spotting non-compliance becomes easier. Despite the challenges, investing more is always wise to stay compliant. After all, your business reputation depends on it. 6. Physically protect your network You can have the best software or service provider to protect your wireless networks and access points. But they will still be vulnerable if physical protection isn’t in place. In the cybersecurity space, the legend has it that the most secure network is the one that’s behind a closed door. Any network that has humans nearby is susceptible to cyberattacks. Therefore, make sure you have appropriate security personnel at your premises. They should have the capability and authority to physically grant or deny access to those seeking access to the network on all operating systems. Make use of biometric IDs to identify the employees. Also, prohibit the use of laptops, USB drives, and other electronic gadgets that are not authorized. When creating a network, data security teams usually authorize each device that can access it. This is known as Layer 1. To improve network security policy , especially on Wi-Fi (WPA), ensure all the network devices and workstations and SSIDs connected to the network as trustworthy. Adopt the zero-trust security policies for every device: considered untrustworthy until proven otherwise. 7. Train and educate your employees Lastly, to improve network security management , small businesses must educate their employees and invest in network monitoring. Since every employee is connected to the Wi-Fi network somehow, everyone poses a security threat. Hackers often target those with privileged access. Such accounts, once exploited by cybercriminals, can be used to access different segments of the network with ease. Thus, such personnel should receive education on priority. Train your employees on attacks like phishing, spoofing, code injection, DNS tunneling, etc. With knowledge, employees can tackle such attempts head-on. This, in turn, makes the network much more secure. After the privileged account holders are trained, make others in your organization undergo the same training. The more educated they are, the better it is for the network. It’s worth reviewing their knowledge of cybersecurity from time to time. You can conduct a simple survey in Q&A format to test the competency of your team. Based on the results, you can hold training sessions and get everyone on the same page. The bottom line on network security Data breaches often come at a hefty cost. And the most expensive item on the list is the trust of users. Once a data leak happens, retaining customers’ trust is very hard. Regulators aren’t easy on the executives either. Thus, the best option is to safeguard and improve your network security .
